Abstract
A cutting implement comprises a substrate having a cutting edge, and plurality of hardfacing beads deposited on the substrate transverse to the edge of said substrate.
Claims18
A shearing implement, comprising:
- a substrate having a first side forming a major surface, a second side an angled with respect to the first side, and a longitudinal edge formed at the juncture of the first side and the second side extending along the first side of the substrate;
- and
- a plurality of hardfacing beads deposited on said major surface of said substrate, the beads having a length extending transverse to the longitudinal edge of said substrate at an angle in a range of 60° to 120° relative to the longitudinal edge to produce a hardened serrated cutting edge along the longitudinal edge.
A method of producing a shearing implement, comprising:
- providing a substrate having a first side forming a major surface, a second side angled with respect to the first side, and a longitudinal edge formed at the juncture of the first side and the second side;
- and
- depositing a plurality of hardfacing beads on the major surface of the substrate running transverse to the longitudinal edge of the substrate at an angle in a range of 60° to 120° relative to the longitudinal edge to produce a hardened serrated cutting edge along the longitudinal edge.
The method of dam 11 wherein said hardfacing beads are deposited on said implement by a laser cladding process.
A shearing implement comprising:
- a substrate having a first side forming a major surface, a second side angled with respect to the first side, and a longitudinal edge formed at the juncture of the first side and the second side;
- a plurality of hardfacing beads deposited on the major surface of the substrate running transverse to the longitudinal edge of said substrate at an angle in a range of 60° to 120° relative to said longitudinal edge;
- and
- an interface layer having a plurality of interface beads deposited on the major surface of the substrate prior to the deposition of said hardfacing beads.
